Some times when the game crashes/stuck, you might lose your a bit of your progress. Keep in mind that game is in BETA and crashes can happen any time. You will not be given anything you lost in a rollback/crash/stuck as it's responsbility. Please take the time to read the following thread https://pokemonrevolution.net/forum/viewtopic.php?f=88&t=7881#p48834
I am so sorry for your case, however, it will not have any action go further for your case. I will suggest when you back some rare pokemon, relog for force save.
